Title: Roasting and baking oven
IPC: F24C3/02
Filed: 1963-01-02
Abstract: 1,011,677. Ovens. R. T. KEATING. Jan. 2, 1963, No. 223/63. Heading A2A. Rapid baking and roasting is achieved in a closed oven chamber 10 by an aircirculating impeller 34 which maximises the transference of heat by air convection from the chamber's heated walls 11, 12, 13, 14 and 15, to goods being cooked on shelves 17, by drawing air through an opening 33 in a baffle plate 19 and pushing it around the edges of this plate, e.g. to create a violently turbulent flow of hot air in the chamber. The opening between the top wall 14 and the baffle plate 19 is smaller than that between the bottom wall 15 and the baffle plate. The oven chamber has a door 16 and is enclosed within a heating chamber 42 having a refractory or insulating lining 41. Baffles 43, 44 prevent hot air from a gas or electric burner 39 reaching the impeller motor 36 and shaft 35. The chamber 42 has an opening 48 and passage 49 to admit air to the burner which has a thermostatic control 53 on the baffle plate 19. Combustion gases escape through an opening 50.

Title: Fluidic binary counter
IPC: F15C1/12
Filed: 1969-01-02
Abstract: 1,210,361. Fluidic logic. CORNING GLASS WORKS. 2 Jan., 1969 [2 Jan., 1968], No. 289/69. Heading G4P. A fluidic binary counter comprises a fluidic pulse device 44 (Fig. 1) of the kind described in Specification 1,160,825 producing a fluidic pulse of finite determinable length at outlet 46, in response to an input signal at 48, applied to control nozzles 50, 52 directly and over delay line 54, to operate on a power stream from source 56. The outlet is connected over conduits 60 to inlet nozzles 32, 38 of exclusive gates 12, 14 having other control nozzles 36, 42 connected by conduits 62, 64 to opposed outlet passages 20, 18 of bi-stable fluid amplifier 10; whose outlet 20 is connected to a utilization device 68; e.g. a binary counter indicating the number of received fluid pulses and whose outlet 18 is connected to a subsequent counter stage. Bi-stable amplifier 10 receives signals at control nozzles 22, 26 from outlets 34, 40 of the exclusive gates and inlet from fluid power source 30. In operation, fluid is normally emitted from outlet 58 until deflected to outlet 60 by a portion of signal from source 48 through nozzle 50, while the remainder is delayed at 54 and emitted from nozzle 52 to restore the fluid stream after the delay time elapse. Initially a stream from 30 is emitted from outlet 18 of bi-stable amplifier 10, and a portion is fed back over 64 to control nozzle 42 of exclusive gate 14, while a pulse from 48 develops a predetermined duration pulse at 46 to inlets 32, 38 of both exclusive gates. The feedback through 42 vents the inlet at 38 of gate 14 to atmosphere, and the inlet at 32 of gate 12 is emitted from outlet 34 to ocntrol nozzle 22 of bi-stable amplifier 10, whereby the stream from inlet 30 changes over to outlet 20 from which feedback over 62 is applied to control nozzle 36 of gate 12, and utilization device 68 is operated. The next pulse at 46 to inlets 32, 38 of gates 12, 14 is emitted at 40 from gate 14 to control nozzle 26 of bi-stable amplifier 10, while beng vented to atmosphere by gate 12, so that the output of bi-stable 10 changes over to outlet 18 for recommencement of the cycle; " 0 " being represented by outlet from 18 and " 1 " by outlet from 20. The counter is reset to " 0 " by pulsing control nozzle 28 of 10, while it is preset to " 1 " by similarly pulsing nozzle 24. In a modification (Fig. 2, not shown) the exclusive gates are replaced by AND gates. Further similar counter stages may be provided.

Title: Improvements in engine-starters
IPC: F02N15/06
Filed: 1920-01-05
Abstract: 141,325. Eclipse Machine Co., (Assignees of McGrath, W. L.). April 9, 1919, [Convention date]. Turning-gear.-In an engine-starter comprising a driving member or pinion 3 mounted for longitudinal movement on and rotary movement with a rotary member or shaft 1, a follower 6 is yieldingly connected to the member 3 and its longitudinal movement is stopped before that of the member 3. In the form shown, the pinion 3 has internal threads narrower than the space between threads 1<a> on the shaft 1, which is driven by a motor or by hand. The follower 6 rotates freely on the shaft 1 and is connected to the pinion by an extensible coil spring 7. A light compression spring 9 is interposed between the motor casing and a thrust bearing 10 on the follower. On the rotation of the shaft 1, the pinion moves axially into mesh with the engine member 4, the threads 3<a>, 1<a> being held in contact by the spring 9, until the follower is stopped by a collar 1<c> on the shaft. The thread 1<a> then comes into engagement with the rear of the thread 3<a>, further movement of the pinion extends the spring 7, and the pinion is driven through the collar 1<c>, follower 6, and spring 7. If the pinion moves far enough to bear against a collar 5 on the shaft 1, it is then driven directly from the shaft. In a modification, the screw shaft is a sleeve slidably keyed on the shaft of the starting-motor under the control of a spring such as 9, and the threads of the shaft and pinion fit without relative movement.

Title: Improvements in or relating to the manufacture or treatment of textile or other material
IPC: D01F2/28
Filed: 1929-01-05
Abstract: 332,231. British Celanese, Ltd., and Ellis, G. H. Jan. 5, 1929. Yarns &c., treating with gases and vapours.- Yarns, fabrics, &c. made of or containing filaments &c. of artificial silk &c. produced from solutions of cellulose esters or ethers have their lustre increased, or restored, or they are protected from the delustring effect of hot aqueous media, by treatment with dry or substantially dry steam. The process is applicable to cellulose acetate, formate, propionate, butyrate &c., ethyl, methyl, or benzyl cellulose or the corresponding condensation products of cellulose and glycols or other polyhydric alcohols, and to such materials in association with cotton, artificial silk, wool or silk. The cellulose acetate products may be flat, round, semi. round, "tubular" or "voluminous." The yarns &c. may be stretched before, during the commencement of, or throughout the steaming, to an extent which may be beyond the elastic limit. The steaming may be continuous with the production of the filaments &c., thus after leaving the cells in dry spinning or the precipitating bath in wet spinning they may pass, with or without drying, to a steaming chamber. The treatment may be assisted by solvents or gelling agents for the cellulose derivatives as is described in Specification 332,187. In an example, cellulose acetate knitted fabric is treated with steam at 20 pounds per square inch in excess of atmospheric pressure, at a temperature of 137‹ C. Specification 269,605 also is referred to.

Title: Improvements in centrifugal metal casting machines
IPC: B22D13/12
Filed: 1927-01-08
Abstract: 278,560. Croad, A. K., (Sand Spun Patens Corporation). Jan. 8, 1927. Casting-machines; metal-pouring.- Centrifugal casting - machines are rotated at different speeds during and after the pouring of the molten metal by means of an electric motor and automatic controlling-mechanism. As applied to a tilted mould 3 which is gradually brought to the horizontal position during pouring, this movement is used to control the speed. The mould is lifted, as shown in Fig. 1, by hydraulic plungers 9 a three-way valve 19 and' water supply 20. A small quantity of water passes by pipes 24, 25 to a float chamber 26 the valves 24a being adjusted so that the float and mould reach their highest position together. The rise of the float first allows a weighted switch 49 to close, thus, through a relay, closing the main motor switch 55. Then a switch 58 is closed, thus, through a relay, opening a switch 56 arranged across a part of the motor field resistor 101 and increasing the motor speed to about 50 R.P.M. in accordance with the setting of the motor controller 6. Molten metal is then poured into a ladle 12 and the valve 19 is returned to exhaust the cylinders 10 through the float chamber 26. As the mould falls the ladle is tilted by linkwork 14, 16, 17 and as it reaches a horizontal position a signal lamp 65 is lighted by closing of electric contacts 67, 68 and an adjustable stop 40 on an arm 39 tilts a pivoted cylinder 34, Fig. 2, causing a metal ball 36 to roll to the left and thus continue the counterclockwise movement, under control of an adjustable dashpot 42, until it makes contact with a stop 47. The cylinder 34 is connected to the hand operation lever 8 of the controller 6 so that during this movement the rotation of the mould is increased from 50 to 1250 R.P.M. When flow of water to the chamber 26 ceases the float gradually falls, owing to an adjustable drain 29, thus closing the switch 56 across a part of the motor field resister 101 and reducing the speel to 900 R.P.M. As the float reaches its lowest position it opens the main switch 55 and stops the motor. To allow the pivoted cylinder 34 to be returned to its normal position the end of the arm 39 is hinged so that it can be swung to one side by hand, a cam 48 bringing it back into its correct position as the mould is raised. A speed indicator 69, Fig. 1, is provided. In a modification the mould is not tilted and the hydraulic piston 9 is weighted at 80 Fig. 5 so that as it falls it tilts the ladle through linkwork 77, 17 and also the pivoted cylinder 34 by means of stirrup 84.

Title: Improvements in and relating to containers
IPC: B65D45/06
Filed: 1951-01-10
Abstract: 680,403. Containers. HERMET, Ltd. Jan. 10, 1951 [Feb. 28, 1950], No. 709/51. Class 66 In a container 3 having a flexible cover 1<SP>1</SP>pivotally connected to the container body and capable of being pressed on to the latter, the edge 7<SP>1</SP> of the cover which co-operates with the edge of the container body in the closed position of the cover is so deformed that in the open position it does not lie in a plane, but in the closed position after a change of shape due to the action of the closing pressure, it lies flush over its entire periphery on the edge of the container body this last edge being contained in one plane. As shown the flexible cover 1<SP>1</SP> of metal (e.g. sheet iron) is pivotally connected by a mechanism 2, to the body 3 and the closing mechanism consists of a hook 4<SP>1</SP> on the cover and a stirrup 5 on the body 3. The edge 71 of the cover 1<SP>1</SP> in the open position is bent downwardly between the pivot and the closing mechanism 4<SP>1</SP>, 5 on two sides diametrically opposite to one another, and in addition is bent upwardly the highest points of which lie at least approximately in the region of the connection mechanism 2 and the closing mechanism 4<SP>1</SP>, 5. On bringing the cover 1<SP>1</SP> into the closed position in which the stirrup 5 pulls the hook 4<SP>1</SP> downwardly the action of the closing pressure against the effect of the flexibility of the cover material causes the shape of the cover to change until the edge 7<SP>1</SP> fits tightly and evenly over the entire periphery of the edge 6 of the container 3 and lies in one plane ensuring a tight seal. The hook 4<SP>1</SP> integral with the cover 1<SP>1</SP> in the region of the highest point of one of the arches forms a flange which extends laterally over the cover edge and is bent round to meet the floor 81 of a slot 9<SP>1</SP>, also formed integrally with the cover 1<SP>1</SP> and serving for the reception of a sealing material such as a rubber ring, where it is soldered or welded. In the region of the highest point of the remaining arch of the type in Fig. 6 (not shown), the cover has a flange 101 which extends laterally over the edge of the cover, and which likewise is formed integrally with said cover, being bent round in the shape of an eye 11<SP>1</SP>. The flange thus forms a hinge flange which serves as part of the connecting mechanism 2. The container body may be of wood or other non-flexible material and the body and cover may be of polygonal cross section.

Abstract: 920,672. Punching-machines. SARO (ANGLESEY) Ltd. Jan. 1, 1962 [Jan. 9, 1961], No. 899/61. Class 31 (2). [Also in Group XXII] A punch comprises a spring-returned plunger 4 which is slidable in a sleeve 3 mounted in a support 1 and has a punching tip 9 detachably secured to its lower end as by a collet 10. A spring 6 acts between the head of the punch and the sleeve and a further spring 7 extends between the sleeve 3 and support 1 for the purpose of urging the sleeve towards a withdrawn position. When the head 5 of the plunger is acted upon by a press, it displaces both the plunger and sleeve against the action of the springs 6, 7. After the punch has penetrated the work and the press has been released, the sleeve and plunger are returned by the springs 6, 7, the punch being stripped from the work by its withdrawal through a stripper bush 13 secured in the end of the sleeve by means of a spring clip 14. Instead of providing a travel-limiting stop for the plunger in the form of an inturned end 16 of the spring 7 engaging a slot 15 in the plunger, the stop may be formed by a flange arranged on the lower end of the plunger for engagement in a recess in the sleeve. In this modification, the upper end of the sleeve is flanged to provide a seat for the springs 6, 7.

Patent GB-191000575-A (GB)
IPC: D01H1/36
Abstract: 575. Stubbs, W. T, and Stubbs, J. H. Jan. 10. Building - motions. - Relates to building- motions for spinning and doubling machines in which two cams are used, one of which serves to give the ring rail or lifter rail a definite lift, while the other serves to raise and lower the limits of such lift, repeatedly, in order to wind bobbins tapered at both ends. A cam 6, Fig. 1, oscillates a lever 15 and so reciprocates a rod 24, a box-frame 26 and a frame 30 connected with the lifter lever, and a cam 28 is interposed between the two frames, so that, as it is gradually rotated by a ratchet-wheel 28 and pawl 37, which is operated during each reciprocation by a lever and an adjustable stop 38, it alters the effective length of the rod 24 and moves the limits of the lift of the ring rail first in one direction and then in the other. The cam 28 makes more than one revolution during the formation of each bobbin. The second cam may be disposed on a lever operated by the cam 6 and arranged to work in or against a swinging lever adjustably connected with the lifting-levers. A spring stop 84 engages with a wheel connected to the ratchetwheel and serves, when the pawl is disconnected in order to wind on to bobbins with flanges, to hold the parts in position so that the only motion communicated to the ring rail or lifter rail is that of the cam 6. The bracket u is connected by means of a loose sleeve with a corresponding bracket on the other side of the frame. The rod 24 is adjustably mounted on a screw in a slot in the swinging lever 15. Specifications 3228/76 and 12,024/87 are referred to.

Title: Special service call routing
Inventor: CATRON NANCY ANN
IPC: H04Q11/04
Filed: 1997-04-03
Abstract: This invention relates to methods of establishing facsimile (fax) connections. If a call is originated from a fax source and the destination is a voice station, then the call will be automatically redirected to a fax machine designated to receive fax messages for the voice station. A fax call is detected by a class of service indication in a local switching office, or by having a number forwarded to a toll office from a local office by Automatic Number Identification (ANI) of the caller that is one of a list of fax numbers. When it is determined that a call is a fax call, a fax indicator is sent with Common Channel Signaling (CCS) messages for that call. If a call with a fax indicator is received in a destination switching office, then the destination office checks to see if the called number is a fax number; if not, translation is made to find the number of a fax station for serving fax calls to the called number, and the call is completed to that fax station. Advantageously, customers need not know a fax number to transmit a fax message to an intended recipient. Three types of problems arise in treating such calls, recognition that the call is a fax call, transmitting that recognition to a far end switch, and redirecting the call at the fax end switch. Among the other techniques used for recognition are a fax class mark in an originating message from an Integrated Services Digital Network (ISDN) line or a dialed prefix such as #, #3, or an alternative common carrier code (10XXX) from an ordinary line. The redirection includes automatic redirection to a store and forward system on busy or no answer, routing to one of a plurality of alternative destinations based on the day and time, screening junk fax, and lighting a fax message waiting lamp on the called (voice) destination. For international calls, a translation from voice to fax may be made at an egress gateway switch; the fax calls may also be automatically routed over low distortion international transmission facilites.
